Product Overview
The Diesel Generator Water Jacket Heater is an essential preheating solution designed for diesel generators operating in cold climates. This professional-grade device warms the cooling water and lubricating oil, preventing them from freezing when temperatures drop below 4°C. In harsh conditions, frozen fluids can solidify, impairing lubrication and cooling functions, which may lead to costly engine damage. By ensuring your generator’s fluids remain at optimal temperatures—down to -30°C—this heater guarantees reliable startups and protects your equipment, making it a must-have accessory for cold-weather reliability.
How It Works
This water jacket heater features an intelligent, automated heating process powered by a microprocessor:
- Start-Up: Press the start button to activate the heater; the indicator light illuminates, signaling the system is operational.
- Initial Circulation: The pump runs for 60 seconds to circulate the fluid.
- Temperature Assessment: If the water temperature exceeds the preset upper limit, the pump stops. If it’s below this threshold, the heating element activates.
- Heating Phase: The heater warms the fluid until it reaches the target temperature, then the heating element shuts off.
- Cooldown Cycle: The pump runs for an additional 60 seconds before stopping.
- Ongoing Monitoring: The controller continuously checks the temperature. If it falls below the lower limit, the pump restarts, and the cycle repeats to maintain the set temperature range.
Press the start button again to stop the process manually. This smart system ensures your generator’s coolant stays within the ideal temperature range for seamless performance.

Installation Guide
For optimal performance, follow these installation steps:
- Mounting: Position the heater horizontally, securing it with screws. Align the water flow with the arrow on the unit, ensuring the outlet faces upward.
- Wiring: Connect to a 220V power supply using 1.5mm² flexible wires. Access the junction box on the outlet side, thread the power line through the cover, and crimp the provided terminals onto the wires using a specialized tool. Connect the terminals to the internal leads (yellow-green wire is the protective ground), ensuring a firm and reliable connection.
- Pre-Start Check: Before powering on, verify the heater is installed below the lowest water level, all air is expelled from the system, and it’s fully filled with water.
Installation Precautions
Proper setup is critical to avoid damage and ensure functionality:
- Vibration Protection: Do not mount directly on the engine; use anti-vibration pads between the heater and engine.
- Positioning: Install the heater below the engine’s minimum coolant level, preferably indoors.
- Fluid Recommendations: Use standard water, ideally mixed with the appropriate antifreeze for added protection.
- Avoid Explosive Environments: Do not install in areas with explosion hazards.
